CraftPin is a lightweight quality-of-life mod for Minecraft 1.12.2 that helps you track crafting goals directly on your screen.
Instead of constantly reopening JEI, checking recipes, and counting items in your inventory, CraftPin lets you pin a craft target with a single key. The mod then shows a compact overlay with the required ingredients, how many of each item you already have, and what you are still missing.

Main Features
•Press P to pin the item in your hand.
•Press P while hovering an item in an inventory or JEI to pin that item.
•Press Shift + P to clear the pinned craft.
•Shows required ingredients for the pinned recipe.
•Counts matching items in your inventory automatically.
•Highlights completed ingredients in green.
•Highlights missing ingredients in red.
•Works with vanilla recipes and normal Forge crafting recipes from other mods.
•Includes JEI-friendly tooltip pinning.
•Configurable overlay position.
•Choose between top right, top left, bottom right, or bottom left.
•Client-side only.
•Does not add blocks, items, world generation, or gameplay balance changes.

Compatibility
CraftPin works best with regular crafting table recipes registered through Minecraft Forge. This includes vanilla crafting recipes and many recipes added by other mods.
Machine recipes, such as pulverizer, macerator, alloy smelter, compressor, or similar custom processing recipes, are not tracked yet unless they are also registered as normal crafting recipes.
